java - 无法使用 xstream 将 xml 字符串反序列化为扩展 genericType 的对象

Question

首先，我想展示用于反序列化 xml 字符串的核心代码

    public XMLClient<T> xmlToClient(String xmlString,T t) throws Exception{
    //according to the generic class's name,insert the name after input tag
    //to make the xstream to know which class is going to deserialize to
        String insertClassName = t.getGenericTypeRecord();
        xmlString.replaceAll("<INPUT>", "<INPUT input."+insertClassName+">");
        XMLClient<T> xmlClient = new XMLClient<T>();
        XStream xs = new XStream(new DomDriver());
        xs.processAnnotations(XMLClient.class);
        xmlClient = (XMLClient<T>)xs.fromXML(xmlString);
        logger.info(xmlString);
        return xmlClient;
    }

T 是从超基类扩展而来的一个类。就像

T 扩展 baseInputXml

但是当应用程序运行在

xmlClient = (XMLClient<T>)xs.fromXML(xmlString);

会有错误消息告诉我 XMLClient 中没有匹配的属性。虽然该属性在超 T 类中不存在，但在子 T 类中存在

我希望你能明白我的想法，我真的对这些 genericType 和 xstream 转换感到困惑，谢谢

Answer 1

xs.processAnnotations(XMLClient.class);

此行应编辑为

xs.processAnnotations(XMLClient.class);
xs.processAnnotations(XMLClientsSuperClass.class);
